Did you get the main jets?
Sounds like not.
They are inside the drain for the float bowl and you need a really skinny straight screw driver to get them out.
Use a stripped stranded copper wire, nothing harder than the jet, and run it through a couple times, should do the trick.

Did the same thing last year, replaced my entire ignition system and all it was was dirty jets.
Try that and repost results.

Try running the wire through them, compressed air may not get varnish off, mine looked factory clean but weren't until I ran the wire through them.
Doesn't take long and may solve the problem, worth a try.

i use a couple of strands of stranded wire twisted together. you also may need to do a link n sinc.
